'bool' is defined in random places. This patch consolidates them into a single header file include/linux/types.h, using stdbool.h introduced in C99. All other #define, typedef and enum are removed. They are all consistent with true = 1, false = 0. Replace FALSE, False with false. Replace TRUE, True with true. Skip *.py, *.php, lib/* files. Signed-off-by: York Sun <yorksun@freescale.com>

Based on sources from the Linux kernel (pcnet_cs.c, 8390.h) and

eCOS(if_dp83902a.c, if_dp83902a.h). Both of these 2 wonderful world
|
